Abstract

According to embodiments of the present invention, a memory component is provided. The memory component includes a storage component comprising a resistance changing material; and an electrical contact coupled to the storage component, wherein the electrical contact comprises silicide, wherein the memory component is free of a metal layer between the storage component and the electrical contact, and wherein the electrical contact is free of a metal layer.

Claims (22)

1. A memory component, comprising:

a storage component comprising a resistance changing material;

an electrical contact coupled to the storage component, wherein the electrical contact comprises silicide; and

a dielectric layer disposed within the storage component;

wherein the memory component is free of a metal layer between the storage component and the electrical contact, and

wherein the electrical contact is free of a metal layer.

2. The memory component as claimed in claim 1 , further comprising a further dielectric layer disposed on at least one side of the storage component.

3. The memory component as claimed in claim 1 , wherein the resistance changing material comprises a phase change material.

4. The memory component as claimed in claim 3 , wherein the phase change material comprises a chalcogenide or an alloy of chalcogenides.

5. The memory component as claimed in claim 3 , wherein the phase change material further comprises a dopant.

6. A method of forming a memory component, the method comprising:

forming an electrical contact, the electrical contact comprising silicide and is free of a metal layer;

depositing a storage component over the electrical contact, the storage component comprising a resistance changing material; and

forming a dielectric layer within the storage component;

wherein the method is free of forming a metal layer between the storage component and the electrical contact.

7. A memory component, comprising:

a storage component comprising a resistance changing material; and

an electrical contact coupled to the storage component, wherein the electrical contact comprises silicide, and

wherein the memory component is free of a metal layer between the storage component and the electrical contact,

wherein the electrical contact is free of a metal layer, and

wherein the memory component further comprises a dielectric layer disposed over a portion of the electrical contact, wherein the portion overlaps with the entire storage component.

8. The memory component as claimed in claim 7 , wherein the dielectric layer is disposed within the storage component or in between the storage component and the electrical contact.
